Pinealon chemical structure

Pinealon is a synthetic tripeptide with the sequence Glu-Asp-Arg (EDR), developed within the Khavinson short-peptide bioregulator program at the Saint Petersburg Institute of Bioregulation and Gerontology. Despite its name, it was reportedly identified from cortexin, a bovine brain-cortex polypeptide extract; the 'pineal' designation refers to proposed neuroendocrine effects rather than tissue of origin.

PubChem lists the tripeptide under CID 10273502 with molecular formula C15H26N6O8 and a molecular weight of about 418.4 g/mol. It belongs to a family of ultra-short peptides that the Khavinson group has proposed can interact with DNA and modulate gene expression.

All findings here are from preclinical cell-culture and rodent research. There are no human clinical trials establishing efficacy, and this entry is provided for research and reference use only.

The Khavinson group has proposed that short peptides such as EDR can interact with specific DNA sequence elements in gene-promoter regions, modulating transcription of genes including antioxidant enzymes (for example SOD2, GPX1), neurotrophic factors, and circadian regulators. In this model the positively charged arginine residue interacts with the anionic DNA backbone while the glutamate and aspartate residues provide sequence-specific contacts.

In cell-culture studies, Pinealon has been reported to protect neurons against hypoxia and oxidative stress, reduce apoptotic cell death, and influence melatonin-related and circadian pathways. These are experimental observations and remain mechanistic hypotheses rather than established human effects.

  • Neuroprotection against hypoxia/oxidative stress: Cell-culture studies reporting reduced neuronal death under hypoxic and oxidative conditions.
  • Anti-apoptotic effects: Reports of decreased apoptosis markers in neuronal cultures.
  • Proposed gene/DNA regulation: Studies exploring EDR interaction with promoter regions and antioxidant/neurotrophic gene expression.
  • Circadian and melatonin-related biology: Research into proposed effects on circadian regulators and neuroendocrine pathways.
  • Alzheimer's-related gene expression: Work examining EDR effects on gene expression relevant to Alzheimer's pathogenesis.

What is Pinealon?
It is a synthetic tripeptide with the sequence Glu-Asp-Arg (EDR), part of the Khavinson short-peptide bioregulator program studied for neuroprotection in preclinical models.
Does Pinealon come from the pineal gland?
No. Despite the name, it was reportedly identified from a bovine brain-cortex extract (cortexin); the 'pineal' label refers to proposed neuroendocrine effects, not tissue of origin.
What is the proposed mechanism?
The Khavinson group proposes that EDR interacts with DNA promoter elements to modulate expression of antioxidant, neurotrophic, and circadian genes; it is also reported to protect neurons against hypoxia and oxidative stress in cell studies.
Is there human clinical evidence?
No controlled human efficacy trials are cited here. The available evidence is preclinical cell-culture and rodent research, and the proposed DNA-interaction mechanism remains a hypothesis.
Is Pinealon approved for use?
No. Pinealon is a research-use-only compound and is not FDA approved for any human indication. This entry is for reference only and is not medical advice or a usage recommendation.
